Great reading, thank you. I agree that HR needs to take a long hard look at this but so also do CEO's, executive leaderships teams and every other leader, manager and supervisor. We have known about how much sleep we need for some time now yet we continue to pay for hours worked rather than productivity, we continue to overload people for the sake of the 'bottom line'. Employees need permission to 'nap' for goodness sake, among other things that will generate greater levels of productivity. If business owners, leaders, managers, supervisors would take the time to understand some fundamentals about how the brain works, they may just 'get' it. Get on with it Australia - put some humanity back into the workplace and watch productivity soar, while incidents decrease.
